empty response from copy api

[shivam19]

https://api.dropboxapi.com/2/files/copy_v2

Two cases

1)  id of files in both the input "from_path" and "to_path", 

2) id of folder in "from_path" id of a file in "to_path". 

it gives EMPTY response, with 500 internal server error.

can you provide a specific error message ?

This issue isn't reproducing for me. It's possible there's some other condition necessary to reproduce this.

Can you share the code you're using to reproduce this, as well as some sample "X-Dropbox-Request-Id" response header values for these errors? That would help us investigate. Please don't post your access token though. Thanks in advance!

Hello Greg,

Thank you for your response.

I have tried this from postman only.

In postman, I am getting 500Internal Server Error.

URL : https://api.dropboxapi.com/2/files/copy_v2

Req Body : 

{
      "from_path": "id:FHpvNWBYUsAAAAAAAAAAag",
     "to_path": "id:FHpvNWBYUsAAAAAAAAAAdQ/new"
}

Thanks for the additional details! I'm able to reproduce this now.

It looks like this can happen when you specify a "to_path" value of a ID for a file with an extra path component appended on ("/new" in your case). Since the file ID is already for a file, you can't add an extra path component. (Files can only be nested inside folders, not files.) I'll ask the team to return a better error in this case.

Instead, you should supply the path where you want to put the file copy (like "/folder/newfile.ext"), or a file ID (like "id:FHpvNWBYUsAAAAAAAAAAdQ"), or the ID for a folder with a sub-path appended (like "id:ABC1234"/newfile.ext" where "id:ABC1234" is the ID for a folder).

Hello Greg,

Thank you for the explanation.

We are writing web-services, error handling part. I encountered one more scenario :

If we provide a wrong folder id(which doesn't exist) in "from_path", it gives the proper error message as : 

{

    "error_summary": "from_lookup/not_found/...",

    "error": {

        ".tag": "from_lookup",

        "from_lookup": {

            ".tag": "not_found"

        }

    }

}

But when we give a wrong folder id in "to_path", then it gives an empty response body with 500 internal server error.

Thanks for the report! I'll ask the team to fix the error reporting in that case too.
